RAI LWAY-TRAI N PROTECTOR.

SPECIFICATION forming part of Letters Patent No. 507,349, dated October 24, 1893. Application filed June 30, 1893 Serial No. 479,290.- (No model.)

T0 a/ZZ wiz/0m zit may concern:

Be it known that I, LEONARD ELISABETH CATHAEINUS JAN BEEESTECHEE, a subject of the Queen of the Netherlands and a resident of The Hague, Netherlands, have invented a new and useful Improvement in Railway- Train Protectors, of which the following is a specification.

This invention relates primarily to railway rolling-stock, but involves a track, or rails at least, of peculiar construction.

It consists in certain novel combinations of parts hereinafter set forth and claimed.

The general objects of the invention are to protect railway trains against derailment, and thus to provide for running such trains at high speeds, and at the same time to increase the safety of railway travel. The objects of the several combinations will be understood by those skilled in the art from the following description of the parts.

Three sheets of drawings accompany this specification as part thereof.

Figure 1 of these drawings represents a cross-section through the track of the railway showing that main-portion of the protector which is carried by the train partly in section. Fig. 2 is a view at right angles to Fig. 1, partly in section and partly in elevation. Fig. 3 is a plan view of the trussed frame detached. Fig. 3a represents a cross-section on any of the lines marked a in Fig. 3. Figs. 4

-to 7 inclusive are sectional details enlarged from Fig. 1. Fig. 8 is a sectional detail on a smaller scale, showing a lubricator; and Fig. 9 is a diagram illustrating the proposed mode of switching the protected trains.

Like letters and numbers refer to like parts in all the figures.

In carrying this invention into effect in the best way now known to me, the carrying Wheels A of the trucks of the engine tender and all cars are united in pairs by rotary horizontal axles B, somewhat heavier and stronger than those commonly used; and each axle is provided with two pairs of fast collars 10 near the respective carrying wheels, and with a tight sleeve-ring 11 between each pair of collars; such rings in common with certain other wear-resisting parts being of very hard steel known as diamond steel and hereinafter so termed. As the axles rotate, each ring revolves in contact with diamond-steel balls 12, suitably confined within an endless groove, as in Figs. 1, 2, 6, 7, and 8, in communication by a passageway 13 with a suitable lubricator C, Fig. 8; such groove and passageway being formed within the loop-shaped head 14 of a short vertical shaft D, which depends from the axle B as in Figs. 1 and 2. The sides of said head, or loop as it is hereinafter termed, and the opposing inner faces of said collars 10 have coincident annular grooves concentric with the-axle, provided respectively with rings 15 of diamond steel, and with diamond-steel balls 16, Fig. 6; and the collars are further provided, outside of said grooves and concentric therewith,with annular dustguards 17, Fig. 4, either metallic or of guttapercha or the like, which, in the formhere shown, are sprung over beads 18 on the collars, and project almost into touch with the respective sides of the loop.

Each vertical shaft D is provided in turn, near its lower end, with a pair of collars 19 20, between which a horizontal guard-wheel E rotates when it comes in contact with the contiguous rail F of the track; the opposing faces of the guard-wheel and collars have coincident annular grooves, concentric with the shaft, provided respectively with rings 21 of diamond steel and with diamond-steel balls 22, which may be similar in all respects to those shown at 15 and 16 (Fig. 6) and above described; and the wheel is turtherprovided at both sides with annular dust-guard rings 23, Figs. 1, 2 and 5, outside of said rings 21 and balls 22, and concentric with their grooves. In the form represented these dust-guards 23 (Fig. 5) are of gutta-percha or the like, and are sprung into dove-tailed grooves in the wheel. The wheel is also provided with an anti-friction bushing or lining ring 24: of suitable metal.

Between the collar 19 and loop 14 of each vertical shaft, it is provided with circumferential flanges between which it is embraced by loops 25 at one corner of a light trussed frame G, shown detached by Figs. 3 and 3a as above, which is suitably constructed of bar steel; its function being to prevent any deflection of the guardfwheels, or, in other words, to keep them in correct working position, whatever the velocity of the train or the inclination of the track may be.

Nuts 26 screwed on the lower ends of the shafts D, and pins 27 for locking the same, in combination with loose collars 20 opposed to fast collars 19 integral. with the body of the shaft, illustrate suitable joints and fastenings to provide for assembling the parts as above. Such details are omitted elsewhere to prevent confusion. They will readily be supplied by machinistsskilled in the art., and form no part of the present invention. Lubricators (3,01` other suitable lubricators, may be attached wherever they are required; the balls and their ooacting rings may betransposed relatively to each other and otherlike modifications will suggest themselves to those skilled in the art.

Each guard-wheel E is further constructed with a peripheral tread 2S matching a laterally projecting guard 29 on the rail F, and with a deep peripheral fiange 30 which projects beneath snch guard as in-Fig; 1. The rails should furthermore be of ample height, and as strong as may be required, and securely united by means of a heavy base 31 with me tallic cross-ties. The shape of the rails is immaterial, so long as they are adapted tocoact as above with said guardwheels E to prevent derailment, and at the same time to coact efficiently with the carryingl wheels A of.

the train, as in Fig. l.

For switching or shunting protected trains, I have adopted what I term switch bridges H, Fig. 9, sliding on steel bearers at right angles to the main track I, as indicated by dotted lines in the figure, and moved by hydraulic steam or electric power. The rails of these switch-bridges or switches will be ysubstantially similar to those shown at F, so

as to maintain the coaction of efficient guards with the guard-wheels E, to prevent derail-` ment.

It will be apparent that with such construc- -tion of the rails and rollingY stock, it is only horizontal axles, vertical shafts depending from said axles, guard-wheels on the lower ends of said shafts coacting with said guards of the rails, and means whereby said shafts are braced against deflection, for protecting such vehicle against derailment in the manner set forth.

2. In combination with a suitable track the rails of which haveinwardlyproj ectingguards, a railway vehicle having carrying wheels on horizontal axles, vertical shafts depending from said axles, guard-wheels on the lower ends of said shafts having peripheral treads which coact with the inner surfaces of said guards and peripheral fianges atbottom which project beneath said guards, and means whereby said shafts are braced against deflection, substantially as hereinbefore specified.

3. In a railway vehicle protected against derailment, the combination of thehorizontal axlesof twopairsof carrying wheels, verticalshafts depending.from` saidaxles between the carrying wheels and` nearthe latter respectively, horizontal guard-wheels on the lower ends of said shafts,.and a trussed horizontal frame having corner loops which cmbrace the respective shafts abovesaid guard- Wheels, substantially as hereinbeforc-speciiied.

4. In a railway vehicle protected against derailment, the combinationi` of carrying wheels on rotary horizontal axles, said axles being further provided with pairsof collars fast thereon between said wheels, vertical shafts having loopsat their upperends which embrace said axles between said collars, and are in turn provided withpairsof collars at their lower endsand\. guard-Wheels rotating between the collars last named, substantially as hereinbefore specified.

5. In a railway vehicle protectedF against derailment, the combination with each guardwheel of a vertical shaft having a pair of co1- lars the opposing surfaces of which have grooves concentric with the shaft, the interposed Wheel having grooves coincident with `those of said collars and annular dust-guards `external to said grooves, and anti-friction `balls and opposing ringswithin said grooves,

substantially as hereinbefore specied.

6. In a railway vehicle protected against derailment, the combination Witheach guardwheel and its shaft ot" a subjacent rotaryaxle provided: with a pairof collars having annular grooves concentric with the axle and` annular dust-guards external to said grooves, an interposed loop at the upper end of the shaft having grooves coincident with those of i said collars, and opposed to theaxle, andantifriction balls and opposing rings within said grooves and between said loop and the axle, substantially as hereinbefore specified.
